IMPROVEMENT IN CHEESE-VATS.

The Schedule referred to in these Letters Patent and making part of the same.

the stop-cocks one way the water in the tank, after.

passing through the heater, becomes warm, and rcturns directly into the tank, without passing into the pipes of the cheese-vats; and also in such a manner' that, by turning said stop-cocks the other way, the water in the tank, after passing through the heater, becomes warmed, and, instead of directly returning to the tank, passes through the pipes of the cheese# rats, and, having been cooled by transmitting its heat through the metal of the pipes to the water lying around saidpipes and between said tin and wood'en vats, shall then return to the tank to be reheated for a second, third, or more journeys back through these same pipes; the objects of my invention being to obtain, whenever desired, a continuous current of water of any desired temperaturethrough the pipes described in the foregoing rst part of my invention, iu order to heat the water between the wooden. and i'n'i vats, and thus heat the milk or cheese within the :in rats to any desired temperature, aud by said ar- .rangementto use the same water over and again General Description.

A (sec plate 1, figs..1 and 2) is the wooden cheesevat', within which is a tin vat.

C 0 are pipes running along the sides of the wooden vat-A, near its bottom, and connected at one end, by means of brauch pipes, with the supply-pipe j ofthe heater.

cl d are continuations of the pipes C C, placed at thevend of the vat connecting the sain pipes C C with the return-pipes.

e is the return-pipe, running along the center of the bottom of the vat.

A is connected at one end with the return-pipe la. of the tank.

X is the heater.

Y is the tank. y

K is a pipe leading from the tank Y, and is connected at its outer cud with the pipe m.

'm is a pipe connecting the upper end of the pipe K witlrthebottom of the circulating heater.

fis apipe connected with the top ofthe circulating heater. i

l isa pipe connected at its lower end with the pipe f. at its middle with the pipe h, and at its upper end with a pipe S leading into the tank.

u.- ware branch tubes connecting the pipe f with the pipes C C of the vats.

Z is a branch tube connecting the pipe C ofthe vat with the return-pipe h.

A stop-cock, No. 2, is placed in pipe f, between where pipe l joins j, and when the branch tubing 1r' n' connects with f a stop-cock, 3,.is placed in the pipe P, between the pipe h and the pipe j'.

A check-\-'alve, 4, is placed in the pipe K, between the pipe m and the tank Y.

. Y is a small. pipe connected at its lower end with the pipe in, and having its upper end curved down.- ward directly over 4the tank operates is follows. V(Sec iig. 2.)

'lhc tankYis filled with water. The stop-cocks Nos. 2 and 3 (scc plat-e) are turned so as to shut ott'` all ow of water from the tank or heater'into the pipes within the checsc-vats, and so as to permit the water to flow freely from the tank into the circulating heater, and to iiow back again into the tank. A fire is then started in the circulating heater. This warms the water in the heater. rihis water, on heilig heated, rises in the heater and passesout into the pipe f, and, not being able to pass the stock-cock 2, flows up through the pipe I, and returns through the pipe S into the tank Y. As this water is passing up and back to the tank, a new quantity of colder water passes out through thc pipe K and down through the pipe m into the lower portion of heater, tortakc its place, and thus a constant circulation of water through the tank and heater is kept 'upuntil the water has become warmed. When thus heated the stop-cocks 2 and 3 are reversed. The warm water then passes through the heater as before, and becomes more highly heated and partially converted into steam, then passes through the heater through the pipe f, and, being checked by the reversed stop-cock 3, passes directly turn-pipe e to the pipe h.

communicate their' heat to the water lying around them and between the tin and wooden rats. This water between said vais, on being heated, heats inturn the tin vat and the milk or cnrd within said tin vat.

This water in the pipes C C, thus imparting its heat' by conductors'of inetal'and water to the I nilk or curd, passes on through the pipes d d and through the rc- Fronr It it pas-ses into and through the upper part ofthe pipe P, and then, passing through the pipe S, returns tothe tank Y, to

again be warmed by the heater and perform as many more similar circuits as desired. y\Vhen the tin vat and vits contents have become suiiiciently heated the water from the heater andthe tank is shut ofi' from the vats by reversing-the stop-cocks, when the water will circulate through the tank and heater.

AA steam-boiler may be substituted for my present heater and tank.

1 Iv do not prppose to patent theeonstruction of the heater, as this may be of any known form for a circulating heater. Such heater may be a plain cylinder, without fines or any other complications, crit may consist ofa plain cylinder with lines, crit may be constructed Aof pipes, or of any required form or shape, ad infinit-mn, no particular construction or form of the heater being essential to my present invention. Said invention is not for a new furnace orheater i'n which the heat is generated; but, after the heat is generated,

tin vat tp any andthe saine required-degree of temperature, yet this hot water and steamfrom it will lhereinbefore mentioned.

consequently rendering said heater more economical and more durable, as it is u'ot likely to burn out.

I wish to state further that inpractice it may be' found desirable to placel the heater below the level of the vat yor rats, so that, as the heat carries the water when hottest to the highest point of circulation, (as

.said water is cooled by transmitting its heat to the water in thc.vat,) the return-pipe shall have a gradual descent toward the heater, so that the gravity of the water will aid in producing the. circulation.

As regards the use ot' a-s'team-boiler, it will be readily seen that when connected to pipes arranged in a cheese-vat on the plan hereinbefore described, the steam-boiler becomes at once, and is, a circulating heater, and operates in exaetl y thesame way, except that as no water-tank is required on -top of asteau1- boiler to supply it with water, it itself 'holding much more water than a heater made for circulation only, the returnlpi'pe h will have to' be conneetedbelow the water-line, while the yhot-water o'r steam-pipe F will be connected above the water-line. \Vith this slight dilierence a steannboiler will be connected in the same manner, operate in the same way, and be as useful as any other style ci' circulating hea ter.v

Claim.

The arrangement, in relation to a cheese-vat, of the sul'ipiy-pipe f and supply-pipes w lw and C O, elbow pipes d d, and return-pipes e and Z, or their equivalents, substantial] y as described and forthe purposes HENRY' W; MILLAR.
